(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
Great concept!! At the beginning, I thought this might be overpowered, but it turned out that clever level design could turn the power in a total hindrance. Some levels gave me trouble (starting from the second one to get accustomed XD), especially the last one.
This is a mix of puzzle and platform. I feel that sometimes, merely jumping on a single vertically moving platform was hard, but it may be a question of getting used to it.
I thought many levels were well designed. Some were more straightforward, such as the one (I do not know the number, sorry; by the way, you could display it!) where you just have to fall between red horizontal platforms. Or I was lucky, but merely rushing when the vertical tunnel was vacant did the trick. X)
I do not know if any other game somewhere used this idea, but it is both simple and clever. There is potential for a lot! :)
(By the way, just putting here that my game is pending until I get the submission form.)
